Founded in 2015, Quantum Systems specialises in unmanned aerial systems (UAS), with a focus on advanced multi-sensor drones for both the defence and commercial sectors. The company also develops its own AI-infused software which transforms aerial data into actionable insights for security, defence, public safety and industrial applications.
Frontline, for its part, is a two-year-old company specialising in unmanned aerial and ground systems designed for reconnaissance, combat, and electronic warfare environments. Its products, which include the “Linza” bomber and “Zoom” reconnaissance drones, have been certified to NATO’s standards and are already being used by more than 40 military units.

Frontline only recently closed a $800,000 seed round of funding from Ukrainian and international investors. And now, Quantum Systems has procured 10% of Frontline for an undisclosed sum, with the option to increase this stake by up to 25% over the coming year.
The partnership is designed to foster a “deeper industrial, technical, and strategic cooperation” between the two firms, building on existing synergies while helping Frontline to expand availability of its technologies, including its Zoom and Linza drones.
The deal also formalises a memorandum of understanding signed by the two companies back in April , which in turn builds on their participation in Brave1 , an initiative established by the Ukrainian government in 2023 to foster greater collaboration between state, military, and private sector operators working on defence issues.
And already this particular collaboration is bearing fruit. Frontline says it has started integrating a “broader pool of European-sourced components facilitated by Quantum Systems” into its own robotic systems.
“This partnership goes beyond capital – it reinforces our shared vision and accelerates our mission to scale battlefield-proven technologies and turn real frontline feedback into next-generation military robotics,” Frontline CEO Yevhenii Tretiak (pictured above with Quantum Systems’ co-CEO Florian Seibel) said in a statement.
Mykhailo Fedorov , from the Ministry of Digital Transformation of Ukraine, said that he expects the partnership will boost manufacturing capacity in Ukraine and deepen ties with the wider European defence sector. But he also positions such tie-ups as an effective way for global allies to fast-track frontline testing in Ukraine.
“Ukraine’s defence tech ecosystem enables international partners to operate at a high tempo, developing systems, testing them directly on the battlefield, and rapidly implementing changes based on feedback from frontline troops,” Fedorov wrote on social media.
Strategic investments are playing a sizeable role in Quantum Systems’ growth, a trajectory which saw its revenue increase 100% year-on-year to €115 million in 2024 . This has included snapping up Germany-based copter drone company AirRobot , which catapulted Quantum Systems to tier-1 supplier status with the U.K. Ministry of Defence. Elsewhere, Quantum Systems also bought the U.K. arm of Nordic Unmanned , a provider of high-end drone products and services.
Aside from Quantum Systems, other European defence tech startups to attain unicorn status include Helsing , a Germany-based military drone and AI software maker which hit a $12 billion valuation back in June . And Portugal-based dronemaker Tekever raised an undisclosed sum back in May as part of a £400 million investment in the U.K., helping it to surpass a £1 billion valuation .
